Reese Witherspoon would "investigate" someone she was considering dating.
The ‘This Means War’ actress – who married second husband Jim Toth last year – would use social networking websites to her advantage if she were still single.
She said:
"It’s a benefit and a curse having social media at your fingertips, where you can investigate the people you’re dating."
The 35-year-old star is amazed at how some people manage to date multiple partners as she has always struggled to find the time to focus on one relationship.
she said: "I have never dated two people at the same time. I wouldn’t know how to keep up with two – I can barely keep up with one!
"Is it OK for a woman to do that? I have no judgement on people who do, as long as they are honest."
